[R9 390] DVI Port reporting 'No Signal' to my ACER S240HL Moniter. It worked 10 days ago?!

[LetsFlip]

Hi guys, I got a strange one for you...

 

So I went on holiday for 10 days and when I come back I am justing having issues, no idea what happened.

 

Before:

So before going on holiday I had both moniters working fine (extended and working).

 

After Holiday:

I returned to my PC working all fine, but my second moniters on the DVI port just seems to not be working.. Not sure what the issue is.

 

The facts:

• S240HL is detecting the cable plugged in. Picture below:
• I have tried HDMI on both moniters, to confirm both moniters are working.
• I have tried DVI slots on both moniters. Does not show the moniters on either, so its not the Moniter DVI slot.
• It worked 10 days ago, no cables removed or edits made over the 10 days, pc was off.
• Used AMD's tool to confirm all of my drivers are up to date, they are, still no issues.
• R9 390 has 2 DVI ports, so I swapped it between the 2 to see if it was that paticular port, this also did not work for either moniter. (DVI Slot).
• HDMI has worked the entire time.

Any thoughts anyone?

Is it on the right source mate (I know it auto-selects but you can tell it to listen to DVI)?

Did you make sure its on the right source?

I have had similar issues with this on my R9 290, but via the HDMI port.

First I reset the BIOS, see if this worked, which in my case it did.

Check to see if the GPU is seated correctly, you may think it is but it may not.

Try a different cable if you can check if its the cable with a damaged pin.

If you can also, try a DVI to VGA adapter, this may tell you that there is something wrong with the DVI connector on the card (Which they shouldn't be.)

 

Have you done any overclocking on the card? if so this could have done something and may require resetting (Switch to iGPU if you can to do the diagnostics.)

Also switch to iGPU first in BIOS, then diagnose in Windows, check the drivers and maybe reset them to defaults.

 

Although I do not see why you are using DVI over HDMI these days, even 1 and 1.2 works okay for normal screens

Try theirs first, could be this simple lol

Screens don't have source select. They are moniters not screens. My mistake.

 

To repeat, the screen DOES detect the cable being plugged in, but does not display the source (my pc).

 Just checked, GPU looks to be set correctly, I haven't done any BIOS stuff.

 

I will have to google how to do the other things.

To enable iGPU, go into the BIOS and look for a GFX setting, on Gigabyte it is shown as PEG (PCI-E Graphics) switch that to IGPU and then its detection mode to IGPU, this will make the IGPU be the main adapter for video, plug it in via HDMI pref.

It's a monitor not a screen? I can use source on both my monitors.

Still not fixed this issue.
